Status Report: Computerization of old IAUCs

This is a status report detailing the current progress on the computerization of the old International Astronomical Union Circulars (IAUCs).

There are three stages to computerizing a circular:

photocopying the original circular to 150 percent of original size
scanning of the photocopy and conversion of scanned image into a text file using OCR
editing of OCR'd file to correct mistakes made by the OCR process

(The photocopying is done partly because the printed circulars have a typeface that is slightly too small to be OCR'd accurately and partly to obviate the need to transport old, fragile circulars to the scanner.) The easiest (although by far the most boring) stage of this process is the photocopying. The scanning is time-consuming as there is no sheet feeder on the scanner that we use in the CfA Computation Facility. The final editing can be the most time consuming as the scanning process can make a real mess of tables. When the OCR'd files have been edited they are put on-line in batches of 50 or 100.

FLASH! As of 1997 Aug. 21 14:30 EDT the photocopying has been completed and the end of the scanning is in sight!

FLASH! As of 1997 Aug. 27 12:00 EDT the scanning and OCR'ing is now complete.

FLASH! Don't expect to see all the IAUCs online for (probably) a year.

The table below gives the current status of IAUCs 1-3799. There are 38 columns each with 100 rows. An entry in column x and row y is to be interpreted as being IAUC (x*100+y). If the circular has been OCR'd, the relevant entry will be `s'. If the circular is on-line, it will contain `*' and the table contains a clickable link to the on-line circular.

Please ensure that you have read our WWW policy on the availability of circulars.

Please ensure that you have read our WWW policy statement.

This computerization project is proceeding under the general direction of Gareth Williams. The editing of the scanned circulars and the conversion to HTML is by Williams. The major portion of the photocopying and scanning was undertaken by Timothy Spahr (1997 June-September), with some assistance from Jennifer Owens (1997 July-August). This is very much a spare-time project. We attempted to get some outside funding to undertake this project, but were turned down. However, we felt that it was very important to have all the IAUCs available in electronic form and have decided to proceed, even in the absence of additional funding.
