The West African Ebola Epidemic Turns One

Anniversaries are often occasions for celebration.  Not this one.  As the World Health Organization (WHO) reminds us, we are now one year into the deadly Ebola epidemic that has claimed the lives of thousands of persons in Guinea, Liberia, and Sierra Leone.  Fortunately, it appears that a turning point in the epidemic may have been reached.

WHO has recently issued a series of 14 papers that examine this first epidemic of Ebola virus disease in West Africa, including Introduction; Origins of the Ebola epidemic; Factors that contributed to undetected spread; Guinea: The virus shows its tenacity; Liberia: A country and its capital are overwhelmed; Sierra Leone: A slow start to an outbreak that eventually outpaced all others; Key events in the WHO response; WHO technical support – a lasting impact?; Modernizing the arsenal of control tools: Ebola vaccines; Classical Ebola virus disease in DRC; Successful Ebola responses in Nigeria, Senegal, Mali; The importance of preparedness – everywhere; The warnings the world did not heed; and What needs to happen in 2015.

These reports reveal several of the facets of Ebola.  First, there’s the Ebola virus itself.  Then there’s Ebola virus disease.  Then we have the Ebola epidemic, as well as vaccines to prevent the disease and various therapies to treat the disease. 

A WebDewey search on "Ebola" retrieves 0 records (!), even when searched against All Fields.  To find where works on any of the facets of Ebola should be classed in the DDC, we need to know a little more about the virus first.  The website for the Centers for Disease Control and Prevention (CDC) provides us with the information that we need:   "Ebola is caused by infection with a virus of the family Filoviridae, genus Ebolavirus."   Or we could go to the MeSH browser, where a search on “Ebola virus” would lead us to this entry for the MeSH heading "Ebolavirus":


A search in WebDewey on "Filoviridae" takes us to 579.256 Single-stranded, enveloped RNA viruses, where Filoviridae is in the including note.   This provides us with both one number of interest to us (i.e., the number where the Ebola virus should be classed) and the kind of virus that it is (i.e., an RNA virus).  An example of a work on the Ebola virus itself, classed in 579.256, is Ebola and Marburg viruses: molecular and cellular biology.

Searching on "RNA virus*" takes us also to 614.588 RNA virus infections and to 616.918 RNA virus infections.  Of course we need to know the hierarchy above 614.588 and 616.918 to know the meanings of those classes and how they differ from one other.  We find:



Ascending the upward hierarchy of 614.588, we come to 614 Forensic medicine; incidence of injuries, wounds, disease; public preventive medicine, of which we are concerned with the incidence of disease and public preventive medicine.  A little investigation takes us to 614.4 Incidence of and public measures to prevent disease, which has a class-here note reading, "Class here epidemiology," and a see reference reading, "For incidence of and public measures to prevent specific diseases and kinds of diseases, see 614.5."  So we find that 614.588 is the epidemiology of RNA virus infections (including Ebola); Ebola epidemics would be classed there.  Since Ebola is in standing room at 614.588, we can’t add Table 1 notation to indicate when and/or where the epidemic is taking place.

What about vaccines for Ebola and other preventive measures?  We find 615.372 Vaccines, which has a class-elsewhere note reading, "Class use of specific vaccines with the disease in 614.5, e.g., use of influenza vaccines 614.518."  The anticipated literature on Ebola vaccines will thus be classed with Ebola preventive medicine in 614.588. 

Scanning the hierarchy above 616.918, we find 616 Diseases, which allows us to recognize that 616.918 is the appropriate class number for Ebola virus disease.  Again, Ebola is in standing room there, so we cannot undertake any number building to express a more specific element of the topic.  An example of a work on the Ebola virus disease, classed in 616.918, is Tara C. Smith’s Ebola.

What about treatment of the disease?  Under 615.5 Therapeutics, we find a scatter class-elsewhere note instructing us to "Class therapies applied to a specific disease or group of diseases with the disease or group of diseases in 616–618, plus notation 06 from table under 616.1–616.9, notation 06 from table under 617, or notation 06 from table under 618.1–618.8, e.g., therapies for cardiovascular diseases 616.106."  Thus, even though, for example, general works on immune serums are classed in 615.37 Immunologic drugs and immune serums and general works on antiviral drugs are classed in 615.7924 Antiviral agents, works on their use in treating Ebola are classed in the number for the disease, i.e., 616.918.  Because Ebola is in standing room at 616.918 (as mentioned previously), we cannot add 616.1–616.9:06 Therapy or any of its subdivisions (despite the explicit [but only general] instruction to do so).

ACAT Best practice for reclassifying fraudulant nf to fiction

Posting to Autocat concerning the story about Alex Malarkey’s The Boy Who Came Back from Heaven

On 20/01/2015 8.14, Moore, Richard wrote:
This sort of invites the question, why wasn’t it classed as fiction in the first place?

Of course, catalogers are supposed to be “unbiased” which actually means accepting any premises of the item we are cataloging. So, if a book claims to be a non-fictional record of travels with space aliens into Alpha Centuri, or people who talk with elves, or that the ghost of Mozart took them over and wrote a new symphony, as professionals we are not supposed to question that. So, this story of a young boy who went to heaven and returned had to be cataloged as if it were non-fiction, no matter what were the opinions of the cataloger.

Just because something has been proven wrong, or even was completely made-up–which happens quite often, as for example, Harry Houdini unmasked many spiritualists, but even today in science and journalism (e.g. the Jayson Blair debacle at the NY Times), does it mean that an item, cataloged under the conditions I described, should be reconsidered as fiction? Although this book turned out to be a lie or falsified, it did not portray itself as fiction.

One of the most famous of this type of deception is “Papillon” by Henri Charrière, which was made into a great movie with Steve McQueen and Dustin Hoffman. All made up, but I see it is still classed in HV at LC.

I would hesitate re-classing as fiction, because it is not. It turned out to be an untruth which is something entirely different from “fiction”.

Sometimes it can be difficult to determine if something is fiction vs. non-fiction, but that’s why we get paid the big money(!).

Ebook on Visualizing Cataloging Concepts

I have just written a small pamphlet with the rather long title of, “A visual explanation of the areas defined by AACR2, RDA, LCNAF, LC Classification, LC Subject Headings, Dewey Classification, MARC21″

I wrote it because I have seen non-catalogers very often mix-up these different terms. I wanted something visual so that people could see how, when they mention, e.g. MARC, then that is not the same as talking about AACR2 and so on. It is primarily visual with a minimum of text.

Also, I have been wanting to do an ebook for awhile. I have made a few but this is the first I have decided to share. This book is very simple to show that MARC and AACR2 and Subjects are different and should not be mixed up.

You can download the book from my blog at There are different formats you can choose. If somebody wants another format, let me know.

I decided not to add it to Google Books, but I could change that decision.

Please share this posting with others who may be interested.

Several people have noted that EAD is for “finding aids” but not “library catalogs.” So there is this separation between finding aids and the catalog. I have not been involved in creating “finding aids.”

In traditional practice, a finding aid is considered equivalent to an index into the greater resource (the special collection the finding aid describes). Catalogs exist to give access to the “greater resources,” i.e. an entire serial or a special collection. Therefore, in the catalog we find records for the “greater resource,” and any indexes are mentioned if they exist–but the actual contents of an index are not included in the catalog. Therefore, in cataloging terms, the finding aid has been considered to be similar to the 500 “Includes index” note, just putting it into a 555 note.

There was also a concern that adding entire finding aids to the catalog, each one describing thousands and thousands of individual records for each letter within someone’s correspondence, or for each note or doodle, would skew the catalog so much that the catalog would no longer provide a fair view of what can be found in the library.

Today, such considerations have been thrown out since the “single search box” brings it all together, for better or worse. I am unaware of any debate on these matters, but I think a debate would still be worthwhile. Still, we hear that “the single search box is what the public wants!”

Is it really what the public wants? I don’t know. It would make for an interesting discussion and an interesting research project.

I’ve heard several people who have replied both on and off list say that DACS is similar to RDA in my cataloging world. And that the output for DACS is often EAD, which is used for finding aids … at least, I know I’ve seen DACS and EAD linked together quite a bit in comments. But you still want the DACS content to end up in a record for the library catalog, right?

Yes and no. Some information does, and other information does not. For example, here is a finding aid in EAD from Princeton:

and the catalog record is here (I hope the link makes it),1&=&=&=&=&PID=wpihzGf94erSFnP9t5a6Tbj1eKN (the title is “Chess papers of Eugene B. Cook”). There is a description of the entire collection in the catalog record, but there is also a link to the finding aid, where there is folder by folder information. Some finding aids have even more detailed information than this one.

When we examine the finding aid, we see that a lot of specific information is left out in the library catalog, e.g. “Carpenter, George Edward, 1844-1924: Problems correspondence”. So, if you search in the library catalog for Carpenter, George Edward, 1844-1924, you find only some books, but not the individual correspondence (under another form of name Carpenter, George E. (George Edward), 1844-1924). If you search him in the finding aids, you get his correspondence but not his books.

While the information for the individual folder could be in the library catalog, Princeton has decided it should not, and they should be searched separately. Today, federated searching could change that in several ways, searching both with one search and perhaps presenting the results in a tabbed display, one for library catalog, the other for finding aid results.

Link Rot, Content Drift, and Reference Rot

The Internet is a fluid machine and the pages that make up the Web are only representative of the present. Links to web pages from last year, and sometimes even last month, are frequently obsolete. As these references become more common in published works, from law review articles to Supreme Court decisions this breakdown evidence supporting arguments progressively becomes more problematic.

    Question on RDA Relationships asked at Google+ Community "RDA Cataloging"

    Question on Relationships in Resource Description & Access on Google+ Community RDA Cataloging - Answers from Experts at RDA-L

    I face a difficulty when recording a work relationship for a work which is a review of a critical edition of another work.

    Ideally, I would like to be able to connect between a work (the review) and the expression of another work (the critical edition).

    Here is an example:

    WORK A: Baalbaki, Ramzi, born 1951. [Review of] Harun's edition of Sibawayhi's Kitab (2010)

    WORK B: Sībawayh, died 796?. Al-Kitāb (ca. 780)

    EXPRESSION B1: Sībawayh, died 796?. Al-Kitāb (ca. 780). (Critical edition by H. Derenbourg, 1881‒1885). Text. Arabic

    EXPRESSION B2: Sībawayh, died 796?. Al-Kitāb (ca. 780). (Critical edition by A. S. Hārūn, 1966‒1977 ). Text. Arabic

    WORK A1 is a review of EXPRESSION B2.

    What do you suggest I should do? It seems that the relationship designators (here, "review of") apply either between two works or between two expressions but not between a work and the expression of another work.

    But here, WORK A itself, not one of its expressions, is a review of EXPRESSION B2. How should I record this relationship?


    Response by Heidrun Wiesenmüller, Professor of library science at the Stuttgart Media University (Germany)


    I have no easy solution, but I agree there is an oddity here.

    RDA indeed seems to restrict relationships to work-work and expression-expression, with no "cross-overs". Whereas this may be o.k. for other types of relationships, it doesn't fit descriptive relationships of the type you mentioned.

    You're quite right to think that the review of a certain edition is a work in its own right. Of course, the review work has at least one expression of its own. But it would be weird to record the relationship only between one expression of the review work and the reviewed edition. This would miss the point that *all* expressions of the review work describe the reviewed edition. So the relationship should indeed be recorded between a work (the review) and an expression of another work.

    It's interesting to compare the situation on expression level to the descriptive relationships on the level of manifestation and item (J.4.4 and J.5.2):
    - description of (manifestation) A manifestation described by a describing work.
    - description of (item) An item described by a describing work.

    So in these cases, RDA allows to record a relationship between a describing work and a manifestation, and a describing work and an item. It seems to me that the same should be possible for a relationship between a describing work and an expression. So perhaps J.3.3 needs to be changed according to the pattern of J.4.4 and J.5.2 (I assume a proposal would be needed for this).

    By the way, one might argue that these "descriptive relationships" between group 1 entities are really subject relationships, and shouldn't be here at all. They do stand out rather.



    Response by Gordon Dunsire, Chair, Joint Steering Committee for Development of RDA

    Salman, Heidrun and others
    These issues are addressed in a submission from the JSC Technical Working Group to the JSC for its November 2014 meeting:

    Response by Heidrun Wiesenmüller, Professor of library science at the Stuttgart Media University (Germany)

    Thanks, Gordon, that's great.
    I haven't worked my way through all the documents yet, so had missed the fact that the proposal is already there :-)

    Do I understand correctly that the descriptive relationship designators (with the proposed revisions and additions) would stay in Appendix J, i.e. still belong to section 8 (Relationships between works, expressions, manifestations, and items). So there is no plan to move them to section 7 (subject relationships)?



    Response by Gordon Dunsire, Chair, Joint Steering Committee for Development of RDA

    The JSC will discuss any improvements to RDA Toolkit associated with the Technical Working Group's recommendations in due course. There are no current plans to move the designators - but I think there are other submissions affecting relationship designators (I haven't had time myself to read all of the submissions).

    Response by Robert L. Maxwell, Ancient Languages and Special Collections Cataloger, Harold B. Lee Library, Brigham Young University

    I would do:

    Review of (expression): Sībawayh, ʻAmr ibn ʻUthmān, active 8th century. Kitāb. Arabic (Hārūn)

    It should also be possible to use this access point in a subject field.

    RDA doesn’t explicitly recognize a relationship between a work and an expression, but they happen all the time. In my opinion we should be able to record relationships between any FRBR entity and any other FRBR entity, as appropriate.

    LibraryThing Recommends in BiblioCommons


    Does your library use BiblioCommons as its catalog? LibraryThing and BiblioCommons now work together to give you high-quality reading recommendations in your BiblioCommons catalog.

    You can see some examples here. Look for “LibraryThing Recommends” on the right side.

    Quick facts:

    • As with all LibraryThing for Libraries products, LibraryThing Recommends only recommends other books within a library’s catalog.
    • LibraryThing Recommends stretches across media, providing recommendations not just for print titles, but also for ebooks, audiobooks, and other media.
    • LibraryThing Recommends shows up to two titles up front, with up to three displayed under “Show more.”
    • Recommendations come from LibraryThing’s recommendations system, which draws on hundreds of millions of data points in readership patterns, tags, series, popularity, and other data.

    Not using BiblioCommons? Well, you can get LibraryThing recommendations—and much more—integrated in almost every catalog (OPAC and ILS) on earth, with all the same basic functionality, like recommending only books in your catalog, as well as other LibraryThing for Libraries feaures, like reviews, series and tags.

    Check out some examples on different systems here.

    Rosetta and Comet 67P Churyumov-Gerasimenko: 2014 Breakthrough of the Year

    Science named the rendezvous of the Rosetta spacecraft with Comet 67P Churyumov-Gerasimenko as the 2014 breakthrough of the year. Here is the summary:

    Science's Breakthrough of the Year is the European Space Agency's Rosetta mission to comet 67P/Churyumov-Gerasimenko. In November, Rosetta's lander, named Philae, captured headlines around the world by touching down for the first time on the surface of a comet. Now, the instrument-studded mother ship is keeping pace with the comet as it continues in its orbit, snapping pictures and analyzing the jets of gas that will spew from 67P as the comet nears its closest approach to the sun in August 2015. The information the craft sends back to Earth should give scientists valuable clues to how the solar system formed and where Earth got its chemicals—including the water that makes up an essential component of all known life.

    Here are two excerpts from the 19 December 2014 Science article:

    Whatever data Philae did manage to return will be significant, not least because 67P is just the seventh place beyond Earth explored by a lander. (Venus, Mars, the moon, Saturn's moon Titan, and two asteroids are the others.) Yet the importance of the landing was largely emotional and symbolic. Mission managers have suggested that 80% of the overall science return would come from Philae's mother ship, Rosetta, which reached the comet in August and has been orbiting it ever since, scrutinizing it from as close as 10 kilometers away. That broader achievement, and the cornucopia of information it is yielding, are what Science is celebrating as 2014's Breakthrough of the Year.
    . . .

    Much of Rosetta's power comes from its ability to inspect the comet at close range for months on end. The half-dozen or so previous missions to comets were all flybys that were over in hours.

    More information can be found on the European Space Agency's web site.

    We don’t yet have monographs based on the latest information from Rosetta, but the Rosetta mission was long in the making, and there are works about the plans for the current mission.  The mission was approved in 1993, and the launch was originally scheduled for 2003, with the intention to rendezvous with comet 46P Wirtanen; however, the launch was delayed, the opportunity to rendezvous as planned with that comet lost, and when the spacecraft was launched in 2004, it needed a new target.  The new target comet has its own LCSH: Churyumov-Gerasimenko comet.

    Browsing the Relative Index for "comets" yields two unsubdivided numbers:

    Comets T2--993
    Comets 523.6

    The Table 2 number (T2—993 Meteoroids and comets) is useful only for number building.  The number 523.6—the interdisciplinary number for comets—looks promising.  In the full record for 523.6 Comets, the Hierarchy box shows that 523.6 is the astronomy number as well as the interdisciplinary number for comets:


    The full record for 523.63 Motion and orbits has this class-elsewhere note: "Class motion and orbits of specific comets in 523.64." There is a similar class-elsewhere note at 523.66 Physical phenomena and constitution: "Class physical phenomena and constitution of specific comets in 523.64."

    We look at the full record for 523.64 Specific comets.  Here is the Hierarchy box:


    Only Halley’s comet has its own number (523.642); other specific comets are classed in 523.64. A dissertation about Churyumov-Gerasimenko comet has been classed in 523.64:
    The Emission of Large Dust Particles from Comet 67P/Churyumov-Gerasimenko Constrained by Observation and Modelling of its Dust Trail.
    Two LCSH have been editorially mapped to 523.64 Specific comets:
    Hale-Bopp comet
    Shoemaker-Levy 9 comet

    Here are works about these comets classed in 523.64 Specific comets:

    Everybody's Comet: A Layman's Guide to Comet Hale-Bopp

    The Comet Hale-Bopp Book: Guide to an Awe-Inspiring Visitor from Deep Space

    Radio Observations and Theories of Shoemaker-Levy 9 Comet

    What about earlier works treating the Rosetta mission? The New Rosetta Targets: Observations, Simulations and Instrument Performances, published in 2004, is summarized as follows:

    Includes the papers presented at the workshop on "The New Rosetta targets, observations, simulations and instrument performances", held in Capri, in 2003. This work covers the fields of observations of the Rosetta targets, laboratory experiments and theoretical simulation of cometary processes, and the expected performances of Rosetta experiments.

    Rosetta’s ten-year trip to Churyumov-Gerasimenko comet allowed for secondary scientific targets—e.g., flybys of two asteroids—but the table of contents shows a heavy emphasis on comets, some chapters relating to comets in general, many focusing on Churyumov-Gerasimenko comet. The table of contents also has much about the special instruments and systems for observing Rosetta’s targets—but it is not limited to instrumentation. This work has been classed in 523.6 Comets.  Another version, published in 2011, seems to have the same table of contents, but has been classed in 523.64 Specific comets; probably the classifier felt that there was enough emphasis on the new main target to justify classing by predominance in 523.64 Specific comets.   

    Another work, Rosetta: ESA's Mission to the Origin of the Solar System, is summarized as follows:

    ROSETTA: ESA's Mission to the Origin of the Solar System is partially reprinted, with updates and corrections, from Space Science Reviews journal, Vol. 128/1-4, 2007. This is the first hard cover book on Rosetta to discuss science and instrumentation.

    This work has information about Churyumov-Gerasimenko comet but more about the Rosetta instrumentation that could be used for any comet—and yet it is not limited to instrumentation. It has been classed in 523.6 Comets.
