Introduction
This section contains information on the practices for transcribing specimen data from specimens into a Microsoft Excel worksheet using the data entry template (File:Data Entry Template 20-Feb-2007.xls).
Contents
Procedures
Sort Specimens
Sort the specimens by collecting event (Locality, Date, Collecting Method, Collectors) for a taxon (scientific group). Do not mix up the taxa. If the specimen labels appear to be entirely heterogeneous, this step may be skipped.
Barcode Specimens
Apply the unique identifier (barcode) to the bottom of the specimen careful to avoid the encoded barcode area of the media. Some pins will have a blunted tip making it difficult to penetrate the barcode media. In this case, use a loose pin with a sharp tip to carefully pierce but not fully penetrate the media. The slight piercing of the barcode media will avoid potential "spinning" of the label in the future.
If you come upon a misprinted barcode whether it be the encoded part being smudged or a digit being unreadable, do not use! The barcode is used to uniquely identify the specimen unambiguously. If the barcode number is not correct, the reference in the database for that specimen will not be correct, thus causing a number of serious problems if not rectified quickly. Copying the correct barcode number is extremely important!
Save New File
Open the data entry template and save the file according to this standard: [most specific taxonomic name for all specimens in drawer]_[collection or location that the specimens belong to; empty if OSUC specimens]_[the date for today].xls
Examples:
- Scelio_AEIC_22-Mar-2007.xls
- Misc_Scelionidae_Colombia_17-Feb-2007.xls
- Misc_Coleoptera_06-Apr-2007.xls
Each drawer or box of specimens should be entered in a single file. Do not overwrite the data entry template file and always begin from the data entry template.
Transcribe Data
Transcribe the specimen labels into the Raw Data worksheet of the spreadsheet. Each label of the specimen will correspond to the numbered label columns in the worksheet with the top-most label being label1. Copy all of the label data as is including any misspellings, incorrect information, or apparently extraneous characters. The goal of transcribing specimen labels is to have as close to an electronic reproduction of the labels as possible. Any additional information about the specimen that does not have its own column such as condition, preservation medium, etc. should be added into the comments column. Any supplementary specimen identification information should also be included in the comments columns to avoid the loss of any useful information.
Any of the columns that are not needed for transcription (i.e. type, life_status, etc.) can be removed with a few exceptions, but new columns cannot be added. If a column is inadvertently removed, the removed column can be re-added but must bear the exact same column name. Reference the data entry template for the original column names. A few columns are required to be present within a data entry spreadsheet: date, name, comments, at least one identification column, and all of the label columns. Do not remove these columns.

Specimen Container Marking
When transcription of all specimens is completed, place a Post-it Note or another form of adhered stationery on the finished drawer or box. Finding a specimen post-transcription is far easier when the specimen container is marked after specimen transcription. There will always be transcription mistakes, so finding offending specimens quickly and easily is essential.
Mark the specimen container in the following format:
- Into Excel: [date finished]
- By: [your name]
- Filename: [data entry filename]
Example:
- Into Excel: 18-Apr-2007
- By: Joe
- Filename: Misc_Scelionidae_USNM_15-Apr-2007.xls
Transcription Notes
- If a specimen has an ambiguous identification, use the parent taxon above the uncertain taxon. Examples: Paratelenomus / Telenomus => Telenominae; ? Maamingidae => Proctotrupoidea; nr. Parascelio => Scelioninae; Trissolcus cf. basalis => Trissolcus; Telenomus n.sp. => Telenomus
- A determination label at the top left of the unit tray applies to all of the specimens subsequent to that label unless a noticeable demarcation is present. This means that the determiner and the determination date will apply for all of the specimens as well as the taxonomic name.
- If an ambiguous identification is used as defined above, put the determination in the comments column. The exception to this rule is for a specimen with a determination label attached to it. Since the determination label will be transcribed along with the rest of the labels, only the first specimen will be missing the determination in the comments for a determined series. Example:
genus species ... comments ... label2 Breviscelio ... ... Breviscelio n.sp., NF Johnson, 2007 Breviscelio ... Breviscelio n.sp. ...
- Every few specimens that have different labels, go back and re-read the label data to see if any obvious transcription mistakes were made. If you have any doubts about the veracity of a transcription, go back to the specimen to assure that the copied label data is correct. Quality always takes a priority over quantity.
