To register for the first time - simply go to Google Scholar Citations and click on create a new account (in upper right corner). Once you have registered, follow the directions to locate your publications in Google Scholar and pull them into your profile.
If you already have a Google account, simply sign in and then look in the upper right hand corner of the screen for "My Citations."
Export options from Citation Profiles include as a BibTeX file, downloaded to EndNote, Excel (as a CSV file), RefMan, or converted to a PDF.
You can also choose to be notified by email every time Google Scholar finds a new citation to one of your publications.
The Web of Science Core Collection offers the ability to generate an on-the-fly citation report:
Saving/Exporting: At the bottom of the Citation Report is a SAVE option. This will allow you to save the report as a .TXT file only. It is not possible to export the report to Excel, but you can copy/paste the citations and/or charts into a word processing program or Excel file.
PLEASE NOTE: Web of Science Core Collection does not offer the Create Citation Report feature for a cited reference search. It is only available for searches run on the main search page - e.g., author, topic, publication name, address, etc.
Information on Journal Citation Reports can be found on the Journal Evaluation tab.
Web of Science, Scopus, and Google Scholar all offer the ability to generate an author's citation summary, including h-index and a number of other citation metrics. Click on the tabs for each specific database (above this box) to see how.
If you wish to manually generate your own h-index, especially if many of your publications are not included in one of the above databases, see the link below for more details.
Many online journals now provide usage information on the landing page for each article they publish. This can be number of page views or number of times the article was downloaded. The location on the page varies but is usually at the top or on the right side.
If you have published a journal article that is available online but does not provide this information on the page, check with the editor to see if they can provide you with a report of download or page hits for your article. Some editors can also provide information on what the average number of downloads is for a specific journal that you can then compare to your article(s). While usage data is not the same as citation data, it can be an indication of usefulness to other scholars.
