Specimens Prior to 1991

(Why two sections?)

Why two different sections for specimen data?

Specimen data prior to 1991 was included in the first edition of the Bats of Texas and included only basic information. For the second edition of the book, ancillary information such as catalog number, sex, tissue numbers, etc. was collected.

Rather than mix the two sets of data into one table (which would include hundreds of empty cells for specimens prior to 1991), the two data sets were separated and formatted to best display the information.
