Monitoring websites
The contents of websites change and often do so at unpredictable intervals. If you want to be notified when the contents of a website change, without having to connect to it frequently to check, you can set up an alert to notify you of any changes. If an alert can be set up it can solve two problems. Firstly if there is a substantial change to an often-recommended site, you can check up to see if must be re-evaluated for recommendation. Secondly, if data contained in a site is updated at say annual intervals, it is useful to know when the new data becomes available. This is similar to knowing that a new edition of a reference work has been published and needs to be purchased.
Some websites offer to notify subscribers automatically if changes are made, but there are a number of tools available which allow you to monitor changes on any website, eg:

Download an evaluation version of the software from one of the sites given above and use this to set up alerts fro two or three websites you visit frequently. |
