This is a little bit shaky, but let's give it a try. Apart from a programmatic solution where you would have to write your own web-scraping scripts which would construct appropriate URLs for each authors and extract their publication statistics, there might be another, though still quite tedious and technically involved approach.
Harzing's Publish or Perish program (PoP) has a feature called "Multi-query center". It allows you to create a set of queries and then generate publication/citation statistics for each of them in bulk. It is meant to periodically re-generate the citation statistics for a set of queries so that you do not have to laboriously write the queries again and again. Now the technical steps towards your solutions would be the following:
- produce a set of queries corresponding to the list of authors you are interested in;
- update all these queries at once by a single button click;
- save the statistics for all the queries e.g., into a CSV file; and
- extract the numbers you are interested in in your favorite spreadsheet program.
The most technically involved step is to produce a set of queries corresponding to the list of authors you have. If the list is not too long (e.g., up to 50), the easiest method would be to enter the queries manually. In the case you have a very long list of authors (several hundreds), then I would try to generate the set of queries programatically. The PoP program stores the queries you enter in it in a file
Queries3.xml in the corresponding
Program Files folder. The queries are organised into folders, the XML is easy to read. Producing a correct XML file with the queries is a little bit try-error process, but you can easily succeed when you create an empty query with an authors and then using a small script (or you favourite text editor/spreadsheet) copy the query entry and only change the Author attribute of the
