Dear All,

I want to create library reservation on sharepoint 2013. I created 1 announcement (name:books) for book names and created Books reservation history list for reservation history. When item changes on Books it adds reservation begin time,end time , book name, book ID to the reservation history with workflow. For exsaple i reserved book name Domain services on 12 sep 2015 to 20 sep 2015. After me another people want to reserve same time. In that case i want thet system gives information that another user reserved the book earlier.  For that I want to write on sharepoint 2013 workflow thet it filtered the list Book reservation history for the date and give the information. Please advise me how may I do it? I cannot find way to do it. 

I added webparts to the page and created connection between lists. In that case it gives information to the users that in that time book reserved. But after it users may reserve book if not noticed this information
