Guidelines of Entries in Encyclopedia

General Introduction

Encyclopedia is an online reference created and curated by active scholars. It aims to highlight the latest research results, as well as provide reference information for researchers and the general public who are interested in accurate and advanced knowledge on specific topics. Details can be found on the About page.

Types of Entry

Latest advance or review: A presentation of the conclusions of one or several research projects on a single, specific topic, or a general review of a research field. Results could relate to a single field, a research group, or a collective of researchers.

Definition: Introduces new discoveries or concepts, including but not limited to technologies, organisms, models, methodologies, molecules, materials, theories, galaxies, and stars. It introduces the main concepts and ideas and may also include the origin, development history, milestones, leading figures or related people, current status, predictions, future directions, and any other relevant information.

Research project: Scholars can present their research project proposals and expected results. The format is a research plan for studies to be undertaken in the near future. The aim of this type is to collect feedback from other researchers in the field and to inform them of ongoing research, in order to build collaborations and prevent duplicate work.

Conjecture: Similar to a research project, authors can announce future research topics and highlight particular challenges in their field. No supporting data is necessary, but authors should cite relevant previous work and may suggest strategies for tackling the stated problems.

How to Publish an Entry in Encyclopedia

§ 1 New users should register at and activate their new accounts by email.

§ 2 Please check existing entries using “Search” on the homepage to see whether there are any similar entries before you create a new one. Click “Add” to start a new entry and access the entry register page. Users can select their subject and entry type. Note that the title cannot be modified once users have passed this step. In order to increase the exposure time in the search engine, we encourage authors to make the title as short as possible.

§ 3 Proceed to the entry editing page. This is an online editing tool for adding and editing text, formats, figures, tables, and references. Here, there is a short video to show some special functions of this editing tool:

Note: Inserted references can be edited or deleted directly from the Reference section.

§ 4 During the editing process, the draft will be saved automatically once per minute. Users can also save the draft manually at any time. After editing and formatting the contents, finish and announce the entry by clicking the “Submit” icon. The entry will immediately be available online.

§ 5 Entries can have more than one author while still in the draft phase. The creator can share editing rights with others after saving the content of their entry. They should go to the “Revision List” in their profile status and click “Share editing rights”; co-authors can be added or removed using their email address. The invited co-author will receive a notification email and will see the shared entry in their own profile.

§ 6 If the entry has more than one author, the creator can change the author order by moving the email addresses in the “Share editing rights” link. The creator is always the first author in the sequence.

§ 7 As only one user can edit the entry information at a time, others will not have access until the last user has finished.

§ 8 Only the original creator can submit the entry to appear online. All authors will be notified by email when the submission is made.

§ 9 If the published entry is not suitable to be published, i.e., not fit for the MDPI policy or too short to describe the opinion clearly, the Editorial Office has the right to change the status back to draft for re-editing again by authors before submission or delete it directly.

How to Revise Published Entries

Any reader can revise entry content by clicking “Edit” on the entry homepage. This takes you to the entry editing tool, as described above. Via “History”, you can check any previous revisions. The changes made to each version are highlighted: Those in red have been removed from the old version, and those in green are newly added.

How to Comment on Published Entries

Any readers can post a comment by clicking “Discussions” on the relevant entry page. Using the “Add” icon at the right side of title, a new discussion can be created.

DOI Application and Assignment

For some well-prepared entries, authors could apply for DOI for the latest version. The basic condition of well-prepared entry should be as follows:

a. The entry length is longer than 1000 words;

b. At least two experts in the same field have published their comments on the current version in discussion part;

c. There is no copyright conflict;

Once the entry fits for the above two conditions, the author could apply for DOI for the current version from his profile entry list. The editing right would be limited after this application. The editorial office would review the application and announce a pdf file on the entry website with the DOI number once the application is approved. The editing right would be released as soon as the pdf version was announced online. The DOI application and assignment procedure would be shown in the following flow chart:

Besides the basic conditions, the editors judge the application mainly on:

a. Language. English language and style are acceptable with no grammar mistakes or typos;

b. Content. There is no duplicated content with other published materials. The application will be rejected directly if we find plagiarism in the content or unsuitable citations in figures, data, tables, etc;

c. Structure. The entry has a clear goal, structure, and logic. The necessary information is clear and integrated;

d. How scientific it is. The entry is meaningful and helpful for other researchers or master or doctor candidates; there is no similar material published elsewhere.

e. Comments. The latest version has received a positive evaluation or recommendation from other experts in the discussion section. If there are any revision comments, the latest version has considered all of them.
