I am using Bookpedia 5.4.2 under MacOS 10.11.2. Searching by a LCCN number does not find a particular book at the LOC.

1) Under the Book pulldown menu I selected Add...
2) In the Search All window I entered the following LCCN: 00041841 {Enduring Treasures: National Parks of the World}
3) My preferences are set to search LOC first.
4) 58 titles are returned, none of which are for the book in Step 2 above.
5) The LCCN Permalink for the book is https://lccn.loc.gov/00041841

The available interface for an LOC search does not offer LCCN as a search key.

If instead of searching "All" you search only the Library of Congress, and then you "limit" the search to "None," your result pops up right away.

On the "all" search the default is title search. The program is smart and does look for identifying numbers, but there is a check that it needed to be larger than 100,000 to avoid thinking that something like "20000 Leagues under the Sea" is a LCCN search. I say needed as I have updated the next version to accept anything over 1,000 and with 8 digits as an LCCN for the "all" search as well.
