Online Book Logging

Thank you Kayla Morin, Children’s Services at the Goodwin Library in Farmington for sharing the results of your query about online book logging. She reported the following responses: 
We’ve had great success with a free system called Reader Zone.  It logs books and other types of reading goals.  The people who run it are always adding new features and are very attentive to requests.
The system is free and there are no ads in the app or on the website.  You, as a reading program organizer, will receive emails for products offered by Children’s Bookstore if you decide to use the service.
You can see it at www.readerzone.org

Hi Kayla, I highly recommend Engaged Patrons. Their summer reading log is Engaged Readers, and the service is free to libraries who receive less than $1 million per year in total income. We have used it for several years ,and the support is quite good. We used to use Evanced which is pricey and way too complicated for what we needed.
