About me

Literature Searches Support is a part-time one-(wo)man-business (information specialist freelancer), which offers students and researchers help and support with their search strategy in several (bio)medical databases.

Hi, I am Christa Niehot and I have experience with searching for literature for different kind of reviews. In 2001 I graduated from my study of information sciences (IDM) at The Hague in the Netherlands, where one of the main skills was performing literature searches. During my time at the Medical Library of the Erasmus MC (Rotterdam, the Netherlands) I learned how to optimize searches and deduplicate them in EndNote. I have experience with the syntax of Ovid (Embase, Medline, PsycINFO), Embase.com, Web of Science and EBSCOhost (CINAHL).

When your own institutional librarian/information specialist is not able to assist you, and/or you want an extra pair of eyes or hands, you can ask for my help. Refer to my price list for my rates.

I am registered with the Dutch Chamber of Commerce under KvK-number 83542981 and I am also a part of WHO iSupplier.

I have worked on different guidelines for EACTS (European Association for Cardio-Thoracic Surgery).
