Summer Solstice 2017

21 June 2017 marks the summer solstice- the longest day of the year. There will be approximately 14 hours and 59 minutes of daylight today here in Muncie, Indiana.

This means that the sun appears furthest north in the sky and the time between sunrise and sunset is the greatest providing the most daylight hours for the whole year. For example, sunrise was 6:12 am this morning and sunset will be 9:14 pm. On 21 September, three months from now, sunrise will be 7:28 am and sunset will be 7:40 pm (do your own calculations at the US Naval Observatory)- almost 3 hours more daylight (2 hours, 48 minutes, to be exact).

“Hidden” Gems: Citation Linker

If you do not know about a tool, you cannot use it.

The Libraries provide a wide range of tools and services to assist researchers. We are always happy to spread the word about these “hidden” gems, like Citation Linker.

If you have ever found an article in a database that is not accessible in full-text, or come across a citation for a book or an article in print or without an active link, you can search the Libraries databases directly for a full-text version by using Citation Linker.

Select the type of item you are looking for, type in the pertinent information, and click the Find It button. If the citation provides a DOI (digital object identifier), you can type that in by itself- DOIs act as a unique identifiers, like social security numbers for articles.

If found, the article will either open or you will be directed to a page where you can open the article. If it is not found, you will be given options for obtaining the item in print or via Interlibrary Loan.

Citation Linker can be found in the bottom right corner of the e-Journals tab on the Student Research Resources page.
