010 LCCN input practices

Lately I’ve noticed that a lot of libraries no longer input 2 spaces before the LCCN in the 010 tag.

It was always my understanding that the input convention was to enter two spaces before the Library of Congress Control number.  Has this rule changed?  If so please let me know…

RDA implementation date set !

The official announcement from the Library of Congress declares the official implementation date for RDA to be March 31, 2013.  One short year away!

The U.S. National Agricultural Library and National Library of Medicine, as well as the British Library, Library & Archives Canada, Deutsche Nationalbibliothek, and National Library of Australia, will also
target early 2013 for Day One of their RDA implementation.

Many dread the date.  Many feel that it is unnecessary.  Some can hardly wait.  What do YOU think?

Either way, with all of the major libraries choosing to convert to RDA, we smaller libraries will have no choice but to follow in their footsteps.    There are some already choosing RDA and when we download those records we simply cut out the RDA input (with no detrimental affect to our records and no influence on access). With software overlays such as AquaBrowser it seems redundant to implement RDA when many of the goals of utilizing FRBR are covered…  As a cataloguer who strives for consistency, the thought of many different qualities of records in our database is disturbing to say the least.


We use many genres in our marc records.  The most frequently used are those from the Library of Congress ($2lcgft) and the Guidelines on Subject Access to Individual works of Fiction, Drama, etc.  ($2gsafd)

In copy cataloging I often see the acronym $2eflch and although I have tried searching ‘eflch’ on Google, I cannot find its meaning.  Can anyone tell me what the acronym stands for? Also, is there a readily available list of terms?

ISBNs for ebooks

I’ve been cataloging a LOT of ebooks lately and I wonder….

Why is the ISBN the same for epub and pdf versions of some titles – while other titles have two separate and distinct ISBNs for the two formats?  If anyone knows the answer I’d love a reply.

Authorities and coding

I’ve often wondered about the coding LC uses in some of their authority records.    There is a or b coding as to whether the authority should be used as a main or added entry, a subject, or a series.   With a meaning YES and b meaning NO.

If you see aaa then the authority can be used for all three.  baa means it cannot be used as a main or added entry,  but can be used as a subject or series.  bab means it can only be used as a subject.  bba means it can only be used as a series, etc. etc.

Why then do the authority records for airplanes, ships etc. have the coding aab?  This denotes that the airplane CAN be a main or added entry.  When is the last time you saw a work written by an airplane?  Is there any instance when the authorities for airplanes, boats, ships, etc. should display in the author authority database?

WebDewey icons

Many of you will have noticed the inclusion of new icons to identify built numbers and manual notes.

Built numbers are represented by a puzzle piece icon.

Manual notes are represented by a book icon.

Both types of icons are included in search results.  For example, the search results for a search on 005.3 include the manual note 005.3 (identified with the book icon) and the built number 005.3742 (identified with the puzzle piece icon).  The puzzle piece icon also is used to identify built numbers in browse results.  On the individual record display screen, the Manual icon appears next to the number and caption for the Manual note (for example, look at the Manual note for 005.3).   In hierarchical displays for built numbers, the puzzle piece icon can appear anywhere in the hierarchical display for the number.  For example, display the record for 338.47004 Computer industry.  In the hierarchical display, the built number icon appears next to 338.47004, and also next to two built numbers in the downward hierarchy, 338.4700411 and 338.470046.  (If you don’t see the icons associated with the aforementioned examples, it may be because relevant information has been cached in your browser.  If you want to see the icons immediately and do not want to wait until the cache is refreshed, you can press <ctrl> + <F5> inside a WebDewey screen associated with one of the examples, which will cause your browser to reload the cached information.)
