Avoid web scraping or downloading large amounts of content from databases to which the library subscribes. Instead — if the publisher allows text and data mining — they will provide an API or other means of access. This helps provide the data in a stable and secure manner that complies with copyright laws and helps the library comply with the subscription license terms. Failure to comply may lock you out of the content and may jeopardize other library users' access.
Resources available for text and data mining vary by publisher.
Individual publishers typically have restrictions on access and use to comply with copyright law and to prevent strain on their servers. Please read carefully any terms and conditions before proceeding. Most providers limit use to non-commercial, research purposes only.
